There's an issue with an Alpha Release of Ubuntu, what should I do?
I'm trying Natty and after an upgrade I received this message:
"Sorry, you don't have 3d support, install it for your graphic hardware to get Unity or please reboot and select 'Classic session' at startup."
So I want to install 3D support but I don't know how to. My machine is a Sony Vaio VGN-SR29XN Laptop with Intel Graphics, but I would like to know the general instructions.
P.S. : I've no problem with the CLI, I just don't know how to proceed in this particular case (what driver, or program...).
